Modal picker not working on IOS

[dimitriospafos]

I'm getting the following error when calling the .pickDate()

Error: TypeError: application.systemAppearance is not a function. (In 'application.systemAppearance()', 'application.systemAppearance' is undefined) Can't end BackgroundTask: no background task exists with identifier 2 (0x2), or it may have already been ended. Break in UIApplicationEndBackgroundTaskError() to debug.

Which platform(s) does your issue occur on?

• iOS

...
var picker = new ModalPicker.ModalDatetimepicker();
		picker
		.pickDate({
		  title: "Select Your Birthday",
		  theme: "dark",
		  
		  maxDate: maxDate,
		  minDate: minDate,
		  doneLabelColor: new Color('#FFFFFF')
		})
		.then(result => {
		 ...
		})
		.catch(error => {
		  ...
		});

@dimitriospafos Did you solve this issue? I have the same problem...

@acortino No, unfortunately I haven’t. Let me know if you get a solution for this issue please. I’m not using this plugin for now.

Edit: in my case, i was using tns-core-modules 6.1.0 upgrading the deps solved it for me, the function don't even exist in the previous versions
